IMPROVEMENT IN WIND-WHEELS.

Specification forming part of Letters Patent No. 212,008, dated February4, 1879; application led September 14, 1878.

To all whom it may concern.'

Be it known that I, FREDERICK W. ING- HAM, of Falls City, in the countyof Richardson and State of Nebraska, have invented a new and valuableImprovement in find- IVheels; and I do hereby declare that the followingis a full, clear, and exact description of the construction andoperation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and gures ofreference marked thereon.

Figure 1 of the drawings is arepresentation of a side elevation of mywindmill 5 and Fig. 2 is a front view of the fan.

The nature of my invention consists in the construction and arrangementof a windwheel, as will be hereinafter more fully set forth.

The annexed drawings, to which reference is made, fully illustrate myinvention.

A represents the base or tower of my windmill, provided with a hollowinverted thimble, B, in which is inserted the correspondinglyshapedhollow stem C, projecting downward from the frame D. This forms theturn-table or turning device of the windmill; but I do not confinemyself to this construction, as the turn-table may be constructed in anyof the known and usual ways.

In the frame D is placed the hollow main shaft a, which rotates inVsuitable bearings, and is provided in the center with an eccentric, E,for imparting the reciprocating motion. To one side of the frame D, onaline with the shaft c, is secured the vane F. On the opposite end ofthe hollow shaft a is secured 'the wind-wheel, which consists of a hub,b, with a series of radial arms, d, projecting from the same, and in thespaces between said arms is placed a wheel-section, G, consisting of aseries of inclined blades arranged somewhat in fan form, having theirinner ends connected together, while their outer ends are free anddisconnected. -Y

The outer end of each section Gr is hun g,by means of eyes i, upon pinsh, in the outer ends of the arms d, as shown, and the inner end of cachsection is, by a hinged rod, f, connected with a collar or disk, H,placed on a rod, I, which passes through the hollow main shaft d. Thecollar or disk I-I is capable of rotating on the rod I, but is held fromany lateral movement thereon by means of pins or colla-rs x x. The otherend of the rod I is guided by suitable keepers in a longitudinal slot,y, in the vane F, and to this end of the rod is attached a cord orchain, m, which is passed around a pulley, oz., mounted on a stud nearthe inner end of the vane, and has a weight, J, attached v to it. Theaction of this weight is to hold the wheel-sections in the wind. As theforce of the wind increases the sections G are turned more or less outof the wind, thereby pushing the rod I inward and drawing up the weight.As the wind decreases the weight throws the rod outward again, andbrings the wheel-sections to their former places.

From the inner end of the vane F is suspended-a series of auxiliaryweights, L L, made in ring form, and the cord or chain m, which suspendsthe main weight, is passed through the weights L.

lIhe rings or weights L in a full-sized mill will be cast-iron, andweigh some three or four pounds each.

If the wind is strong, the wheel-sections or fans Gopen, and theleverage becomes shorter and more weight is required. As the main weightJ is raised the auxiliary weights L are applied one by one, thusincreasing the weight gradually more and more as the fans open.

The fans are opened from the ground by means of a cord or chain, p,passing over pulleys s s on the side of the vane, and connected to theend of the rod I.

I am aware that wind-wheels have been constructed wherein thewheel-sections have been secured to rods pivoted between the radial armsofthe wheel and operated by jointed levers, as shown in the patent toJesse M. Clock, October 20, 1857. I am aware, also, that wheel-sectionshave been composed of sail-vanes radially insert-ed in grooves in ashaft pivoted between the radial wheel-arms and operated by rodsconnected with the disk upon the wheel-shaft, as shown in the patent toL. H. Bennett, May 29, 1877 but I do not seek in this application tocover either of said constructions.

What I claim as new, and desire to secure by Letters Patent, is

1. In a Windmill havin g a Weight to hold In testimony that I claim theabove I have the fans in the Wind, a series of auxiliary hereuntosubscribed my name in the presence Weights, applied automatically, toincrease the of two witnesses. main Weight in proportion to the increaseof The force of the Wind, as herein set forth. FREDERICK WILLIAM INGHAM.

2. The ring-shaped suspended Weights L, in combination with the mainWeight J cord or Witnesses: chain m, and vane F, as and for the purposeGEO. W. NEELY, herein set forth. R. L. HENDERSON.
